Because you have stated this is multiple units, not a Central system, I wanted to make sure you research if it qualifies. Example: "For split systems, ENERGY STAR certified equipment with SEER2 > 16 is eligible.  All ENERGY STAR certified packaged systems are eligible." And, as noted by sjrcpa, which year you are working on also matters, since the rules can be different. A lot of sales happen with the comment that, "You get a credit for this, which helps offset your cost" but sales people are, well, sales people. There nearly always is an Energy Credit, and almost never much or any Tax credit.

Did you use the Lacerte help article:
